How ELONGATED HYPOCOTYL5 helps protect plants from UV-B rays.
Most of us do what we can to avoid the DNA-damaging effects of UV-B rays. While plants can’t slap on sunscreen, put on a nice hat, or move to a shady spot, they too have ways to protect themselves from (and acclimate to) damaging UV-B radiation. For example, plants undergo UV-B-dependent photomorphogenic changes (see figure), including reduced hypocotyl and leaf expansion, increased stomatal cl...
متن کاملUV-B-responsive association of the Arabidopsis bZIP transcription factor ELONGATED HYPOCOTYL5 with target genes, including its own promoter.
In plants subjected to UV-B radiation, responses are activated that minimize damage caused by UV-B. The bZIP transcription factor ELONGATED HYPOCOTYL5 (HY5) acts downstream of the UV-B photoreceptor UV RESISTANCE LOCUS8 (UVR8) and promotes UV-B-induced photomorphogenesis and acclimation. Expression of HY5 is induced by UV-B; however, the transcription factor(s) that regulate HY5 transcription i...
متن کاملSurvival, the hormonal stress response and UV-B avoidance in Cascades Frog tadpoles ( Rana cascadae ) exposed to UV-B radiation
1. Despite the increasing occurrence of global environmental changes, including increases in ultraviolet-B radiation (UV-B; 280–320 nm), little is known about how factors such as UV-B affect animals physiologically. Amphibians provide a good model for examining physiological effects of UV-B exposure because studies documenting both lethal and sub-lethal effects have been completed on many speci...
متن کاملApplications of UV-B lighting to increase phenolic accumulation of Alo vera L. plants
Since supplemental UV-B radiation can provide a simple and economical alternative to increase phenolic compounds in plants, we evaluated the dynamic biological responses of Alo vera L. plants to different UV-B doses (10 and 30 kJ m−2 day−1). The experiment was performed on the basis of Completely Randomize Design with 4 independent replications. Under high light conditions (600 µmol m−2 s−1), U...
متن کاملSerratia Exposed to UV Radiation Show Increase In Survival Capabilities
The recF, recO, and recR genes were originally identified as those affecting the RecF pathway ofrecombination in Escherichia coli cells. Several lines of evidence suggest that the recF, recO, andrecR genes function at the same step of recombination and postreplication repair. In this work,we report that null mutations in recF, recO, or recR greatly reduce UV-radiation mutagenesis<lb...
